九、發明說明： 【發明所屬之技術領域】 本發明係關於摩托車，且更特定言之’係關於包括排氣 管及消聲器之排氣裝置中之改良。 【先前技術】 在曰本專利特許公開案第2002-37174號中已知摩托車之 ~個實例’其中包括一排氣管及消聲器之一排氣裝置置於 W擎之後方。 揭示於該公開案中之排氣裝置包括一以一大體S形自— 版成引擎體之汽缸蓋之下部分向後方延伸的第一排氣管， —連接至該第一排氣管之後端且在該車輛之寬度方向上延 伸之排氣消聲器，及一連接至該排氣消聲器之一端之第二 排氣管。 一對左及右踏板經由一踏板固持器固定至該引擎體之曲 軸箱之下部分，一側支架經由一支架支撐部件固定至該踏 板固持器之一端。 該第一排氣管之部分靠近其至該汽缸蓋及該排氣消聲器 之連接，在該車輛寬度方向上向外凸出且如俯視圖中所示 向外曝露。此外，與該第二排氣管連接之該排氣消聲器之 —端部分在該車輛寬度方向上向外凸出且如俯視圖中所示 向外曝露。因而’對於所揭示的習知排氣裝置，在排氣管 之外觀及保護方面存在進一步改良之空間。若該等向外曝 言P刀被以某些遮蔽物覆蓋以獲得較好外觀及對該等排氣 管之有效保護，則需要相當大的額外成本。 110353-1000926.doc 1357391 此外，若除了該側支架之外想給上述摩托車提供一主支 架以改良其可用性，則安裝該主支架至該引擎體之後部或 至該踏板固持器非常困難，因為該第一排氣管及排氣消聲 =經安置接近該引擎體或踏板固持器。同樣，因為該曲轴 粕之底部罪近該車體之前端且安裝該主支架至該底部將導 致車體失去在前後方向上之重量平衡，所以安裝該主支架 至在踏板固持器之前之曲軸箱之底部不太好。 此外，若催化轉化器提供於該排氣裝置中用於淨化排 氣，則需要定位該排氣裝置以有效利用該引擎體周圍之小 空間。 亦需要排列該排氣裝置使得即使t水進人該排氣消聲器 時該排虱裝置可以高可靠性被啟動同時使對引擎之負面 影響最少。 ' 【發明内容】 根據本發明，提供一改良摩托車，其包含：一頭管；一 自該頭管向後及向下方向上延伸之主架；一安裝至該主架 之下方之動力單元；提供於該主架之後部之槐轉板；可柩 轉地安裝至該等插轉板之後又，·由該後又支樓之後輪一 置於該動力單元與該後輪之間且安裝至該等拖轉板卜者

INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to motorcycles and, more particularly, to improvements in exhaust devices including exhaust pipes and mufflers. [Prior Art] An example of a motorcycle is known in the patent application No. 2002-37174, which includes an exhaust pipe and an exhaust device of a muffler placed behind the W engine. The venting apparatus disclosed in the publication includes a first exhaust pipe extending rearward from a lower portion of the cylinder head of the engine body in a substantially S-shaped shape, and is connected to the rear end of the first exhaust pipe And an exhaust muffler extending in a width direction of the vehicle, and a second exhaust pipe connected to one end of the exhaust muffler. A pair of left and right pedals are fixed to a lower portion of the crankcase of the engine body via a pedal holder, and one side bracket is fixed to one end of the pedal holder via a bracket supporting member. A portion of the first exhaust pipe is adjacent to its connection to the cylinder head and the exhaust muffler, projects outward in the vehicle width direction and is exposed outward as shown in plan view. Further, an end portion of the exhaust muffler connected to the second exhaust pipe protrudes outward in the vehicle width direction and is exposed outward as shown in a plan view. Thus, there is room for further improvement in the appearance and protection of the exhaust pipe for the disclosed conventional exhaust device. If such outward exposure P-knives are covered with certain coverings for better appearance and effective protection of such exhaust pipes, considerable additional costs are required. 110353-1000926.doc 1357391 Furthermore, if a motorcycle is to be provided with a main bracket in addition to the side bracket to improve its usability, it is very difficult to install the main bracket to the rear of the engine body or to the pedal holder because The first exhaust pipe and exhaust muffler = are placed close to the engine body or the pedal holder. Similarly, because the bottom of the crankshaft is close to the front end of the vehicle body and the mounting of the main bracket to the bottom will cause the vehicle body to lose weight balance in the front-rear direction, the main bracket is mounted to the crankcase before the pedal holder The bottom is not very good. In addition, if a catalytic converter is provided in the venting device for purifying exhaust gas, it is necessary to position the venting device to effectively utilize the small space around the engine body. It is also necessary to arrange the exhaust means so that the draining device can be activated with high reliability even when t water enters the exhaust muffler while minimizing the negative impact on the engine. According to the present invention, there is provided a modified motorcycle comprising: a head tube; a main frame extending rearwardly and downwardly from the head tube; and a power unit mounted to the lower side of the main frame; a slewing plate at the rear of the main frame; after being rotatably mounted to the oscillating plates, the rear wheel is placed between the power unit and the rear wheel and mounted to the rear The tow board 2:: a part of the muffler; and a main bracket that is rotatably mounted to the lower portion of the body in front of the muffler. = The muffler is provided between the engine and the rear wheel, so the muffler prevents the quality from being exposed to the outside and thus it is possible to significantly improve the motorized view. Similarly, an area below the insert plate can be used for the installation space of the muffler 110353-I000926.doc 0 1357391, and thus the capacity of the muffler can be increased. Preferably, the power unit and the muffler are connected to each other via an exhaust pipe, and the exhaust pipe passes through an area between the upper left and upper right support portions of the main bracket, thereby preventing the exhaust device and the muffler substantially Exposure to the outside, and thus, it is possible to significantly improve the appearance of the motorcycle. Further, since the main bracket is mounted on the exhaust pipe and over the exhaust pipe to the lower blade of the vehicle body, it can be easily installed without conflict between the main bracket and the exhaust pipe. Preferably, the main bracket is partially supported by a portion of the power unit located below the lower end of the pivoting plate. Thus, an area below the pivoting plates can be used as the installation space for the muffler so that the capacity of the muffler can be increased. Preferably, the main bracket is positioned to overlap the muffler as shown in plan view. Therefore, compared with the case where the arm members of the main bracket are placed side by side with respect to the muffler substantially horizontally, the present invention can reduce the amount of protrusion of the muffler or the main bracket in the vehicle width direction, thereby reducing the overall size of the vehicle. And improve the appearance of the vehicle. Preferably, the muffler has a recessed portion formed on a lower side thereof for preventing a collision between the muffler and the main bracket. By providing the recessed knives, it is possible to substantially increase the height of the main bracket from the ground surface while fixing the sufficient capacity of the muffler. According to another aspect of the present invention, a modified motorcycle includes: a front door, a main frame extending rearwardly and downwardly from the head pipe; and a power unit mounted to the lower side of the main frame; a pivoting plate at the rear of the main frame; a pivotally mounted to the rear fork of the pivoting plate; a rear wheel supported by the rear fork; and a muffling between the power unit and the rear wheel 110353-1000926.doc. As shown in the top view, the muffler has a chevron shape including a wide front region in which one end portion of the exhaust pipe connected to the power unit is accommodated; and: a longitudinally elongated rear region in which the partition plate and the communication pipe are accommodated, A partition divides the inside of the sounder to form a plurality of expansion chambers. The expansion chambers communicate with each other via a j-connecting tube. The exhaust pipe has an opening at one end that is located above the rear end of one of the tail pipes of the muffler. Thus, even when water enters the muffler via the exhaust tail pipe, it is possible to effectively prevent water from entering the engine through the end opening of the exhaust pipe. As a result, the engine can always be started with high reliability. Preferably, in the present invention, the communication tube has an opening located above the rear end of the tail pipe. According to another aspect of the present invention, an improved motorcycle includes: a head f, a main frame extending from the head pipe in a rearward and downward direction; and a power unit below the main frame a pivoting plate provided at a rear portion of the main frame; a pivotally mounted to the pivoting plates; a rear wheel supporting the rear wheel; a muffler disposed behind the power unit; a connection An exhaust pipe of the power unit and the muffler; and a catalytic converter provided in an intermediate portion of the exhaust pipe in front of the crankcase of the power unit, along the power unit as shown in a plan view The cylinder extends in the front and rear directions. In the present invention configured in the above manner, a dead space formed on the curved moon j and under the alpha cylinder can be effectively utilized, which can reduce the overall size of the motorcycle because the exhaust pipe is along the The vehicle body is disposed in the front and rear directions without protruding in the vehicle width direction and thus is substantially not exposed to the outside, 110353-1000926.doc 1357391 Therefore, the present invention can significantly improve the appearance and effectively protect the exhaust pipe. As shown in the top view, the catalytic converter is placed to overlap the cylinder. Thus, the catalytic converter does not protrude in the light width direction of the vehicle, and thus is not exposed to the outside in general, and as a result, the present invention can remarkably improve the appearance. *The preferred 'muffler' is placed between the power unit and the rear wheel. Therefore, it is possible to prevent the sound-absorbing shellfish from being exposed to the outside, and thus it is possible to significantly improve the appearance of the motorcycle. Thus, the catalytic converter can be placed substantially horizontally below the vapor red.
